Cory's bestie for life Rider Strong has popped the BIG question to his ladylove of many years Alexandra Barreto!!

Congratz to the max you adorable things!

AND the Boy Meets World star convinced his sweetheart to say YES with a hand crafted diamond ring…

Crafted by Rider's own HANDS! Whodathoughtit!

We are SO sad that Rider won't be returning as a regular to his former television world as part of BMW spinoff Girl Meets World, but hey, at least it means he can spend tons more time with his wifey to be!

In July, father John McCain was diagnosed with stage 4 glioblastoma, an aggressive form of brain cancer, which also claimed Beau's life.

When the 33-year-old began crying, the politician went over and consoled her, adding:

"There is hope... And if anybody can make it, your dad [can]."

Biden is also optimistic about "breakthroughs that are occurring now," regarding potential treatment options and cures.

"There's a lot of things happening. Any of you who have somebody who is diagnosed with gliobastoma, which is about as bad as it gets, there's breakthroughs that are occurring now... And it can happen tomorrow."
